Lentil welcome
I think everyone who is in a similar position to us is most welcome and it's nice to have new people to liven up the place.
How far along are you now? Have you booked in with MW yet, as well as your early scan? I had a 7w scan due to what they charmingly call a threatened abortion and you could clearly see the little heart beating, which is ace! I cried 
Pip I may be wrong but I think being pg does weirdo things to your iron levels so even if you are normally fine you might want to specifically get them checked out. They do bloods in early pg where I am, but I'm sure if that's a possibility you can get them done earlier or ask the practice nurse to check a sample for you.
Bushy I have stuck with Pregnacare throughout, and use their Omega+ version which is two pills, one with omega and one ordinary pg multivit. I have to say that barring a few scares I have felt really well this pg, and not been ill at all besides morning sickness. I am also a total sucker for the whole 'helps your baby's brain and eye development' thing! But possibly more money than sense going on 
So the HB MW team dropped off my 29w bloods results last night and they are all normal, including the extra kidney function test which I have to have due to my dodgy renal stuff - in fact, my creatinine levels, which indicate kidney function, have got better during the pg despite pg being supposed to put loads of strain on the kidneys.
Well, I'm not arguing!
Going to see the HB MW next week at home, so it's all going ahead. Cannot believe I am over 30w now (30+4)
